[Hepatitis virus (HBV, HCV, HDV) markers in chronic liver diseases. Comparative studies in two East-Central European countries].
The prevalence of hepatitis virus markers in patients with chronic liver diseases from two countries has been studied: 68 patients (38 alcoholic hepatitis or cirrhosis, 30 chronic HBsAg-positive hepatitis) from Hungary as well as 109 patients (55 alcoholic liver disease, 45 chronic hepatitis or cryptogenic cirrhosis and 9 hepatoma) from Romania were examined for HBsAg, anti-HBs, anti-HBc, anti-HCV and anti-HDV, using the corresponding Abbott Elisa test systems. In alcoholic liver disease HBsAg occurred in 6/38 patients from Hungary and in 22/55 patients respectively, that is HBV markers occurred with significantly higher frequency in alcoholic patients from Romania (p less than 0.05). In the Hungarian group a total of 36 patients were HBsAg positive and out of them 5 had anti-HDV (13.9%), while out of 21 Romania HBsAg carriers 10 patients had anti-HDV (47.6%). Among 9 hepatoma patients 4 had HBsAg, 6 anti-HBs and 7 anti-HBc and 4 had anti-HCV and 3 had anti-HDV. One patient with hepatoma had both HBsAg and anti-HCV plus anti-HDV as well. Results suggest that the infection with hepatitis viruses in alcoholic liver diseases is more common in Romania than in Hungary, and the prevalence of delta virus infection in HBV carriers is also significantly higher in Romania than in Hungary.
